It’s a good night to stay in and binge-watch some Netflix.

Winnipeg and much of southwestern Manitoba is under an extreme cold warning as temperatures dip overnight to make it feel close to -40. Friday’s overnight low is -30°C.

“With the mercury expected to dip below the minus 30-degree mark by morning and light northwesterly winds of 10 to 15 km/h, wind chill values will be in the minus 35 to minus 40 range tonight and dip below minus 40 early Saturday,” Environment Canada says.

The weather office says conditions may warm up slightly during the day on Saturday, but wind chills will remain into the evening and early Sunday.

The blast of cold arctic air is arriving from the north, but if you can toughen it out until next week, temperatures are expected to rise to the single minus digits.

How to dress for extreme cold

• Always wear clothing appropriate for the weather. Synthetic and wool fabrics provide better insulation. Some synthetic fabrics are designed to keep perspiration away from your body which keep you dry and further reduce your risk.
• Dress in layers with a wind resistant outer layer. You can remove layers if you get too warm (before you start sweating) or add a layer if you get cold.
• Wear warm socks, gloves, a hat and scarf in cold weather. Be sure to cover your nose to protect it.
• If you get wet, change into dry clothing as soon as possible. You lose heat faster when you’re wet.
